A709 grade 50W high strength steel and SM490B steel plate belongs to low alloy high strength steel, which is a kind of structural steel produced according to Japanese Standard JIS G3106. Its strength σb is 490MPa. A709 grade 50W high strength steel, SM490B steel plate is mainly used in buildings, bridges, ships, rail vehicles, oil storage tanks, containers and other buildings requiring advanced weldability.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A709 grade 50W high strength steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A709 grade 50W high strength steel steel, can be used as an alloying element of low alloy steel.
The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for A709 grade 50W high strength steel?
